Mississippi River Hits Historic Low for Fourth Year, Disrupting Grain Transport
The Mississippi River south of St. Louis is once again experiencing dangerously low water levels as the region enters the fall harvest season. For the fourth consecutive year, water levels have dropped to critical lows, significantly impacting grain transportation, barge traffic, and cash basis prices at river terminals.
“Lower Mississippi river water levels south of St. Louis dropping to low levels for the fourth year in a row.”
The cause of the ongoing river decline lies in persistent dry conditions extending across a wide stretch of the Midwest and Eastern U.S.
“Continued dry weather from Iowa on east to Pennsylvania and the Tennessee-Ohio Valley resulting in reduced water flows coming from the Missouri River, Illinois and Ohio rivers as well, resulting in what U.S. Geological Service calls zero stream gauge happening for the fourth year in a row and eight of the last ten.”
According to the U.S. Geological Survey (USGS), this troubling trend of “zero stream gauge” highlights an ongoing hydrological crisis that has now occurred in eight of the last ten years. Forecasts suggest water levels will remain low through October, placing further pressure on the grain supply chain just as harvest hits full swing.
“Water levels are expected to remain low through October, severely affecting grain transportation and thus cash basis levels at river points. In addition, barge rates of course increasing. Barges can’t be filled to capacity.”
With barge traffic restricted, operators are unable to load vessels to full capacity, forcing costs upward. Higher barge freight rates are being passed down the supply chain, weakening the cash basis for grains and further squeezing margins for farmers and grain elevators.
“This is the bottom line report.”
On the market front, livestock futures are showing renewed momentum, offering a glimmer of optimism amid transport concerns.
“We’re keeping an eye on December lean hog futures here at midweek. They broke out of a wedge pattern this time last week and challenging those contract highs back from mid-June.”
As water levels remain a critical bottleneck in agricultural logistics, all eyes are on weather patterns, river conditions, and freight markets heading into the final stretch of 2025.
